Description of reference numerals: the paper board comprises an upper layer paper board 1, a middle layer paper board 2, a lower layer paper board 3, a side plate 4, a first sheet body 11, a second sheet body 21, a through hole 31 and a side sheet body 32.
Detailed Description
The present invention will be described in further detail below by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not to be construed as limiting the present invention.
Examples are given.
See fig. 1-4.
The embodiment discloses an inner support box of a packing box, which is used in the packing box and is used as a placing cushion of articles, is made of water-proof and oil-proof laminating paper with heat-sealing characteristics, and comprises an upper layer paper board 1, a middle layer paper board 2 and a lower layer paper board 3 which are consistent in shape and size, wherein the upper layer paper board 1, the middle layer paper board 2 and the lower layer paper board 3 are hot-pressed together from top to bottom.
